Aerodynamic Effects of Inferior Turbinate Reduction

Numerical Simulation of Airflow Fields in Two Typical Nasal Structures of Empty Nose Syndrome: A Computational Fluid Dynamics Study

“…The changes in the ENS-IT models are generally consistent with the results in most previous studies[5,6]: decreased nasal resistance, velocities and wall shear stresses, and more chaotic streamlines. In the ENS-MT models, the changing trends of the measured parameters are similar to, while less remarkable than those in the ENS-IT models.…”

Numerical Simulation of Airway Dimension Effects on Airflow Patterns and Odorant Deposition Patterns in the Rat Nasal Cavity

“…In fact, a very small error (∼34 µm) in the anatomical structure of the model can lead to a significant error in reported nasal flow. Similar results have been reported for nasal structure changes in human nasal cavities, such as inferior turbinate hypertrophy [2], inferior turbinate surgery [5] and nasal bone fracture [50]. One point to note is that, in the OE region, the average velocity in NCMw was higher than in NCMn, which was opposite to what was found in the whole model (Figure 5).…”

Atrophic rhinitis: a CFD study of air conditioning in the nasal cavity

“…The mean total nasal resistance in their patients was 0.12 Pa/(ml/s), while literature reports for healthy subjects are on the order of 0.15-0.30 Pa/(ml/s) (38). The resistance figures calculated by CFD are somewhat lower than the ones obtained through rhinomanometry, as also found in other CFD studies (50). However, it should be borne in mind that by convention, rhinomanometry calculates nasal resistance at a transnasal pressure drop of 150 Pa (6).…”
